If it's just about bowling quick then Ali should learn from Pandya and skill wise Bumrah got nothing to learn from Hasan Ali although if Bumrah wants a over the top celebration of his own then he can acquire it from wannabe chotu undertaker.

Avesh has potential, physique, pace but he doesn't put his mind often into bowling especially when he gets tonked for few boundaries and he goes haywire with his line and length and that's why he didn't get many FC matches last season. Lets us see this year what he brings in his game.

He got talent . He's not in form now but we all know that he's a great timer of the ball.
Coming to my point I meant that of a player is not a great talent than he must be a hard worker and smart worker to get along with Kohli.
